Seconded on Cockpit project w File Sharing.

Probably not best practice, but it's possible to install it on the PVE host itself since its ZFS manager and Identity manager plugins and other features fills some gaps in what Proxmox doesn't do (or would have to drop to CLI to do).

Also recommend RClone in a systemd can take care of various file movements, syncs and backup tasks you may need against the host, vdumps or SMB file shares.

For a few seconds this could have been a shit post. But when you see it, its shitpost.

I can see where you're coming from, and agree, but ISPs in Australia providing services on the National Broadband Network NBN will almost always describe this as a modem router.

It's not uncommon, right or wrong, even Verisign USA describe a modem vs router thus: "The modem is responsible for sending and receiving signals from the ISP, while the router disperses the signal to devices on the network"

So, this doesn't exclusively modulate and demodulate (mo-dem) an analog to digital signal in this case, and 100% it doesn't have the physical hardware to do so, but it is nonetheless required to negotiate ('modulate'?) the internet connection with an ISP, albeit software-defined through digital PPP Ethernet protocols.

All this is a bit off topic, but I hope the OP (or others) may better define the internet service needed, and may determine if this device may be suitable for their requirements.

I'm glad it includes openwrt support for later down the track. It's one of the few AX devices with such support and I chose it specifically for this reason!

Meets definition of a modem/router depending on what physical connection and protocols your ISP provides.

My Ethernet WAN connects to the ISPs NTU (optical fibre network termination unit), but WAN is capable of negotiating PPPoE, PPTP or L2TP with PAP/CHAP. Can also Dual WAN, Port forward, NAT.

The documentation is a little lacking. And no ADSL/VDSL etc. but it meets reqs for some.

Maybe check out the Asus TUF-ax4200 gaming modem/router? Just bought one and it's been an awesome upgrade to my old AC modem/router. Wifi6/AX, 4 core, good ram, 1x 2.5GbE WAN and 4x1GbE LAN. Has USB to take a mobile SIM for dual WAN/failover. ASUSs software is very good, but it is on the support list for openwrt once Asus stop supporting it.

Problems with spinning HDDs on RPI are common. Possibly even on powered hubs they may spike more than rpis 1.2A USB max allowance. You may need a specialised hat, or better to switch to solid state storage?

Suggest the typical hardware device troubleshooting. watch/tail your dmesg -w or kernel log as you add the extra drive. It's curious that the system itself doesn't crash, but from your description it still sounds like a power starvation concern or possibly high temperatures if this device is under heavy load.

Using a voice assistant (like Google assistant), these understand how to treat plurals, so if you use the same base name numbered 1 & 2 you can say: turn on the (base name) lights and both come on without having to try to define scenes or explicit device groups or links. They can still be controlled independently, so I number in a sequence relative distance to the 'entrance' to that room, or left to right, you might want clockwise.

I use names related to the room, area or object, like: entrance light, dining table light, craft area light, fan light, hallway light, tv light, desk light, bed light, reading light, kitchen sink light. Numbered 1 & 2 if needed since usually want them on together.

Or may be further refined by type like: night light, down light, spot light, string light, stand light, lamp, bulb, LED etc.

Hope that helps with a few ideas?

Twin towers Sept 2001?

Doesn't meet your power requirements (only up to 850VA) but i recommend Cyberpower Bric meets the rest. I have mine connected to my Proxmox host, usb passthrough to VM running HassOS with the NUT add-on. Neat little LCD and silent unless humming on battery. Can choose if you want an audible alarm enabled or put it on mute.

APC is still very well regarded UPS brand for small business, and your specs seems like they should be achievable across many leading brands. Have you looked into latest models for your spec?

Maybe share a list of candidates you're considering and can get opinions on those?

Agree. Best to have that dedicated hardware, and a degree in network engineering first! Hah :)

If you're starting out, best keep internet facing home services private through a VPN, maybe ZeroTier or TailScale. Don't advertise them publically at all.
